Moustakas, a 22-year-old third baseman, entered 2011 as a consensus top-10 prospect. He was the second overall draft pick in 2007 out of high school after David Price. Since then, Moustakas has cruised through the ranks of the minor leagues. This season, he’s hitting .287 with 15 doubles, 10 homers, 44 RBI and 38 runs in 55 games. He started the season slowly but caught fire after Hosmer’s callup, as if he was motivated to join him with the Royals. He tore up the lower levels of the minors before reaching Triple-A.

Expect Moustakas to immediately take over full time at third, as there’s little reason for the Royals to promote him without playing. Hosmer’s been a fixture in the lineup since he was summoned, so the Moustakas situation won’t be any different. Wilson Betemit will probably be used to spell Moustakas on occasion and also see some time at second base along with Chris Getz.
